Subject: [PATCH 2/3] staging: pi433: Reduce N_PI433_MINORS to conform with N_SPI_MINORS.
Date: Sun, 24 Mar 2024 11:32:00 +0200	[thread overview]
Message-ID: <20240324093201.793485-3-ikobh7@gmail.com> (raw)
In-Reply-To: <20240324093201.793485-1-ikobh7@gmail.com>

The driver can't actually support 2^20 devices.
Current RasPis GPIO pins can actually support only 1 device.
Other or future platforms might support more.
